Up for sale is a Working, in excellent condition Mitsubishi Expo Transmission controller. Should fit many 86-87 4 cyl models. perhaps others as well. See part numbers at the top of the listing. This unit offers a 30
day functionality warranty. As
always with this type of component your best bet is to
match the part number to the one on your original TCU / TCM. A
defective TCM can cause a whole host of problems related to the
transmission. Often times, technicians overlook the TCU and simply
replace the transmission, but the same problems will still exist. If
your transmission is not working correctly - Try the TCU first.
If your car does not
have these issues but you intend to keep it a while, I recommend our
customers keep an extra ECU in the trunk. These units now have to be
special ordered from most dealers new for big $$ (often times over
$1000!), and you can never find one when you need one. Even now
finding a good one second hand is getting to be quite difficult as
these cars get older.
